Abstract:
An abattoir survey was conducted on 244 cattle slaughtered at
Elobied abattoir in North Kordofan state, Sudan, during the period
which extended from March to May 2011. The objective was to estimate
the prevalence of hydatid cysts in cattle and to investigate risk factors
associated with the disease. Routine meat inspection procedure was
employed to detect the presence of hydatid cyst in visceral organs (liver,
lung, heart and peritoneum).
Selected cattle originated from three States: Darfur, Kordofan and White
Nile States. The overall prevalence was 2.5% . The prevalence of hydatid
cysts infection according to age of cattle was 4.4% in animals more than 5
years and 1.2% in animals less or equal to 5 years. The distribution of the
hydatid cysts according to the area (states) of cattle was 3.4% in Darfur,
1.3% in Kordofan and 0.0% in The White Nile. As for body condition the
prevalence was 2.5% in good body condition and 0.0% in poor body
condition. Regarding distribution by sex, the prevalence of hydatid cysts
was 3.0% in male and 1.2% in female. Also, prevalence of hydatidosis in
presence of dogs was 2.8% and 1.4% in the absence of dogs. The
prevalence of hydatidosis in breed of animals was 8.3% in fuga, 2.5% in
Baggara and 0.0% in Kenana. Also, prevalence of hydatidosis when
carcasses not disposed was 2.9% and 0.0% when carcasses disposed.
Univariate analysis by using the Chi-square for each following risk
factors was : breed (P-value = 0.278), age of animal (p-value = 0.120),
origin of animals (P-value = 0.449), body condition (p-value = 0.573),
sex (p-value = o.405), presence of dogs (p-value = 0.523) and disposal of
carcasses (p-value = 0.294) . The risk factors like age, breed and disposal
of carcasses were found significantly associated with hydatidosis ( p-value
≤ 0.30).
Using multivariate to determine the association between hydatidosis and
significant risk factors, only age was found significantly associated with
hydatidosis (P-value = 0.036).
